The World Health Organization has warned the Omicron variant poses a “very high” risk globally.
The body said this variant could lead to severe consequences in some regions.
In a technical note, the WHO said: “If another major surge of Covid-19 takes place driven by Omicron, consequences may be severe.”
It added, “to date, no deaths linked to Omicron variant have been reported”.
The WHO said it expected more data within the coming weeks on the new variant – but confirmed previous reports the variant has an unprecedented number of spike mutations, adding there were considerable uncertainties about the effect these could have.
